I did not use hardware RAID, I use vinum over these 5 drives. Without the patchset system stays up for months acting as ftp/cvsupd/nfsd server without any single issue.

Nope, there are no such errors (I would expect them for CMD-649, but luckily even that beastie works fine) Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
